travel tog our primary tank which is a fairly normal looking manhole. beneath these manholes is a 10,000 gallon primary tank. there are two chambers. the trash chamber which filters out the trash and plastics and the organic solids settle out just as normal wastewater treatment process is. the water then flows to an equalization tank, a recirculation tank, and then on to tidal flow wetlands cell 1a. all those these cells look to be only 3 or 4 feet deep, they're actually 8 feet deep below this concrete sidewalk. the water repeatedly cycle into the cell from the bottom up. as the water comes up into this cell, it meets the microbes here to treat the wastewater. they flourish off the organics found in the wastewater. after multiple cycles, most of the wastewater treatment has already occurred and the water then flows to the vertical

cells located around the corn iron polk street. 2c is located half outside on polk street and half inside in the building lobby. after the final polishing, the water flows to the disinfection room of the basement of the building. there the water goes through two disinfection processes. first ultraviolet light, and second a dosing of chlorine. the treated water is stored in a 5,000 gallon reclaimed water tank where it is pumped throughout the building for toilet flushing purposes. the treatment cycle is complete and the water is reused again and again. this new building features a rainwater harvesting system. rainwater is captured from the building's roof and the children's play area along the side of the building and sent down to our disinfection room where there is a 25,000 gallon sis tern. the rainwater receives minor treatment and is used to irrigate the building's trees and landscaping. >> when we're resues using water we have on-site, we're not purchasing new water and we're also not putting sewage down into the sewer system

which is costs money. this is a demonstration project of 5,000 gallons a day. it is the beginning of understanding and feeling comfortable with this technology that can be scaled up into eco districts and community scale systems, campus-type systems where in those situations when the water is reused and the numbers are much higher, 50,000, 100,000, 200,000 gallons a day, imagine the savings on that that you're getting. you're not purchasing freshwater and you're not using the sewer and being charged appropriately. this wastewater processing and reuse technology is cutting edge. and although it's been successfully implemented in other cities, it will be one of the first such installations in an urban office building. >> here is a city agency that treats wastewater, but they send no wastewater to the treatment facility. that says a lot. >> it's got a 12 gallon per day occupancy using 5,000 gallons per day with a building officing 1,000 people.

that turns out to save over 2.7 million gallons a year. >> the public utilities commission runs water, power and sewer services for san francisco. we can't afford to be out of business after an earthquake. so, we're thinking about building a building. that building is going to hold our operations center and our emergency operations center for things like earth quack. that building had to be immediately occupiable. great. but we can do better than that. so, this new technology that we ended up using was a concrete building that straps basically, that goes through the interior of the building and allow the building to turn or twist as part of an earthquake as it corrects itself. >> in the course for the puc building, we've actually incorporated in addition to that steel that's embedded in the monolithic concrete, specialized high strength cables that are not bonded to the sound concrete, but are

threaded through essentially hollow conduits in the cast concrete. and when those cables are spread, they're actually anchored and they're actively in other floors and pressing down, forcing that concrete wall into a state of compression. and that's the characteristic which allows the building to shake, absorb energy from the earthquake, deform, and also come back to its original geometry. what that meant was the building would be functional. it meant it wouldn't have to be abandoned and fixed. >> we have probably the greatest specification for concrete ever developed for a project that has a really innovative structural system. one of the things that's evident from the research that's been done is that concrete is responsible for a

significant amount of co2 production. and that's worldwide. and we developed a way in which we could incorporate replacement material such as flag and fly ashe to supplement the portable cement and allow a big reduction in those carbon emissions associated with production from that poured cement. >> concrete for the building has a 70% replacement value with recycled materials fly ashe and recycled materials that would otherwise go to waste. reducing our carbon footprint in half. >> the way that we often do buildings in the city are often projects in the city is we go out and we do a low bid. somebody bids on something, we have to do everything that's expected out completely. and everything after that thorable change prosecretary is very difficult. spec ed out. >> we use design bid delivery method. in this one we did a

construction manager gc, which really means that we bring the contractor on board as we design and they participate in the design. it brings a lot of collaboration. >> the department of public works decided to try a more team oriented approach with this project. the best value approach. they really went to to us come on board as a team member and work with them. >> what that meant was the contractor allowing key subcontractors such as the electrical, mechanical, plumbing systems, would always be reviewed and looked at for constructability, for cost constraints, for scheduling. >> and it was a risk for the city. it was a change for the city, it was something very, very different. we met all of our project parameters, the budget, the schedule. we love this project. it is a fantastic example of what can happen when you take a

risk, you do something differently, and you work together. you get a great result. >> one of the things we're going to have in that building is going to be this media wall in the lobby. and that media wall has several things that it can show people, but one of the things it can show our employees and our visitors is how much energy, how much water, what we're using in the building. >> the wall is based on building data. we have total energy use per floor. we also have energy use in the building today that will show information and percentages on how much is being used today versus an average day. there's also information from solar, how much solar the building is producing, and showing the savings from solar. we also have reclaimed water and that will be shown per month. the center section is dedicated

to water, wastewater and power. we have live information showing us how much wastewater has been treated so far from the night before. there is also a twitter feed and information that anyone that comes in can see, you know, current news and information from the twitter. there's also bart information, when is the next bart leaving, when is the next train departing. and there is weather, hetch hetchy, and weather at san francisco. >> the physical arts wall is comprised of 54 feet, 160 high-definition monitors that has a 3-d motion detection that allows you to approach the wall and then to look at the contents that is there in front of you, which is a beautiful artistic narrative. and then as you move towards it, it activates the content that comes up. >> this is one of the applications we developed with communications team at the puc and it's called, and it's about water cycle, how the water comes down from the snow in

yosemite, into the mouth of the reservoir, gets treated, produces power, comes all the way down to the city and gets charged and leaves the bay. we developed a motion tracking system taw four cameras on the ceiling here which detects people when they approach the wall and presents information pop ups. so, you can enjoy it from a distance as a landscape, but once again up close there is another level of information that's educational about this facility. >> fire fly by artist ned con is an art installation which rises straight from the golden gate avenue sidewalk to the top of the building. >> the fire fly wall will be 5 by 5 polley carbon plates that will move with the wind and show a wave effect in the daytime. when those also swing back and forth and they hit the fulcrum,

it will also set up an led light that will cover the fire fly. so, at nighttime people in another part of san francisco can see the side of our building and about 20 feet wide and 10 stories high will be a wall that will flickr on and off like fire flies at nighttime. it will be so energy efficient that if all those lights go on, it will be the equivalent of a 40 watt bulb. and also the new piece of artwork going all the way down the side of the building, which looks like this incredible wind ripples on a pond. and i thought, oh, my god, how incredible, how wonderful. >> inside the building we will have water walls in the main staircase, and the water will be dripping through the side of the wall. you'll be able to hear it, you'll be able to see it. we call the san francisco artists and galleries and said, hey, we want a building that is a place people want to come to work in and to visit. we're now going to be buying

art from between 08 and 100 local artists in san francisco and the arts commission will be hanging in that art the next couple of months in the building. >> we'll have a cafe in the lobby. the cafe will be serving people there. they'll have a child care center on-site so people with children can come to work. if something happens to their child they can walk right downstairs. it has enough space for 65 kids. >> we looked at various ways that we could be creative in promoting alternative transportation. we did this by providing bike racks and showers in the building. we do see the number of parking spaces to two parking spaces and providing electrical charging stations for alternative vehicles. >> it's time for us to have a

home that all of us can be proud of. >> and we couldn't do this without everybody working together on the one goal, which is, let's build something that reflects the honor of hetch hetchy, the honor of the greatest engineering feats, reflects what our puc does for our public, and for generations to come it will educate everybody. >> i'm really proud that one of the greenest and most sustainable buildings is here in norm in district 6. the wind turbine, the solar power, the living machines, recycled water that ed and the mayor has already spoken to. and what's also amazing about this building is it's not just internally, but you can actually see it on the outside. so, when people are walking around the city they can actually see the green and environmental aspects. >> what better way to show that the puc cares about the environment and the puc is going to show everyone else, you can do this, too. and you can do it in a way that makes sense, that's affordable, and that is better for the environment. >> and this is the most energy

efficient government building in the united states today, if not the world. and it is an example that the entire united states can look to and say, that's what we need to do to save our city hundreds of millions of dollars in energy consumption a year and set an example to everybody of how to save energy, to be green, to be sustainable, to be responsible. the city is leading the way. >> it will be immediately recognizable and iconic from various parts of the city or even if you see a picture. that's the sfpuc building. it's a wonderful building. ♪ ♪ ♪

welcome home, man. >> hello, everybody and welcome, good afternoon. thank you so much for coming to join us for this celebration today. i'm renell, brooks moon from the morning show, and of course, the voice of your 2012 world champions, san francisco giants. >> in fact, the last time that

i was at city hall was halloween 2012, right after the parade and the victory celebration and so it is great to be back and it is almost baseball season and who is ready to demand our title? i cannot wait, i cannot begin to tell you how honored i am to serve as your host for this special event, i want to welcome you officially to the san francisco mayor's office of neighborhood services black history month closing ceremony. what a way to wrap things up, we gather here to honor a living legend, ground breaking politician, activist and freedom fighter and fashion icon, the one and the only the honorable willie l. brown junior. [ applause ]

growing in the area, his accomplishments and contributions to the world at large and public service were not lost on me and it is really been a dream come true for me to grow up and get to know him professionally and personally. my father and willie were acquaintances and fraternity brothers. >> when he was elected the first african american mayor i was right up there front and center in 1996 and channel five was out there reporting and they included me in the news coverage and interviewed me and i was historical and crying and emotional and the camera lingered on my black power fist.

and fast forward for when i was in washington, d.c. when i was there for barack obama first inauguration and there i went with my fist again more tears flowing and i was not the only one thinking about the shoulders on which the president stood, including those of mayor brown who without question paved the way for president obama and countness others. so today we celebrate all that he is and all that he has done and all that he continues to do. the san francisco mayor's office of neighborhood services truly appreciates the generous support it has received during this 2013 black history month and so right now, i would like to take a moment and acknowledge our sponsors for today's event, san francisco firefighter local 798.

the san francisco police association. wells fargo bank. comcast. gen renaissance foundation, at&t and paradigm assets management company and thank you all for helping us out today. we also would like to thank marcus shelby of the orchestra who will be blessing us with his talents today. >> now, the san francisco mayor's office of neighborhood services works tirelessly as a liaison between san francisco neighborhoods and city government to make sure that the voice of the neighborhood is heard and if problems and concerns are handled effectively and respectfully. and now, representing the mayor's office of neighborhood services i would like to welcome to the podium, the

director miss cristina, palone. thank you. >> good afternoon. it is my honor and pleasure to welcome each of you to the first black history month closing ceremony, the mayor's office is dedicated to connecting city government to san francisco diverse neighborhood and community, function as to which the information is made available, particularly to those most in need. today we are honoring one of san francisco's greatest legends honorable willie l. brown junior for what he has bestowed on the local government, that he has bestowed on the local government, the state and our over all country. it is because of his exceptional dedication, and

tenacity to fight injustice and provide economic growth and development that i am able to be up here today. could everyone who has worked for honorable brown or was appointed by him, please stand or raise your hand if you are already standing. soak in the impact of a number of people that just raised their hands just then. what a tremendous honor it is to have this particular to say thank you honorable brown for what you have done to help us all grow, and achieve significant heights professionally and personally. lastly, i want to also personally recognize the african american woman in city government who have greatly impacted me on my own professional journey.

supervisor breed, cohen and my regional director rhonda simmons. >> these women have been very instrumental in connecting the legacy that honorable brown established within his own career by giving back to their communities, providing opportunities for advancement and growth, it has been an honor to learn from each of you and particularly to rhonda for giving me an opportunity to learn the grave importance of working in partnership, being transparent and taking time to build infrastructure correctly. i need to also acknowledge all of the staff of mons, please raise your hand or stand. in the back. these young people have dedicated long and countless hours to making all of these events and activities that mons produces as a success, it is because of each of them that they were able to make a

difference. i am honored to lead such an extraordinary group of people, thank you and have a good event. >> thank you, cristina. so proud of you, i have watched this child grow up before my very eyes. she is fantastic. and now, let's welcome the 43rd mayor of the city and county of san francisco, a long-time friend of willie's ladies and gentlemen, mayor ed lee. hello, sir, how are you? >> hello, everybody. >> welcome to the people's palace. very briefly, well, thank you very much for that introduction and cristina willie was joking just a minute ago and said wait a minute, i thought that the

budget cuts you still have the neighborhood services going? and of course, i said, well, i can't tell you everything because you are write for a column in the newspaper and i just always learned the lessons from you and you announced the cut and then you just quietly just hire everybody back and all of a sudden we have a neighborhood services. but i am here tonight to of course, not only to participate in this event, closing out the month of celebration, and focus and renewal of promise and so many of you who are active and leading our african american community together with the rest of the city to make it continue to be a city that i know mayor brown had tried all this year to continue being which is the world class city for everybody.

and this is what i know that willie has done. all of his years, i think that his history is quite clear, not only to everybody in this room for anybody who works within this building knows that every detail of government, whether it is shining the brass in these elevators, to people who work here and the standards upon which they should be serving the public, to great department heads and all of the things that they do to continue the success of this city. mayor brown, has done all of it. and he has paid attention to every detail and i am still catching up to learn, but it is. even to be close to what he has been trying to do and of course, especially this year with the trials and tribulations of i suppose any mayor in their first elected year goes through, you know, i

take a lot of things personally and i must always go back and say, willie, did this happen to you? >> and, of course, getting the great advice that is absolutely necessary, because, when you sit in this seat, and you have the enormous responsibilities and you don't have the 30 years of experience that mayor brown did, but you similarly appreciate what it takes to run the city, to ask for help, and now i am getting a lot of free help from willie and i appreciate that. and it is, it really is, something that he has given time and time again with my predecessor nuwsom who leaned a lot on him and i am doing the same thing and if we get things done, it is a lot to do with making sure that we don't make costly mistakes or anticipate where the problems might be in this very great city.

these are the personal things that i am learning that i need to have a team of people around me that gives me that experience, that knowledge, the connections, that we don't have and it is not just within the city and county of san francisco. if anything, mayor brown has got connections throughout the state, throughout the rest of the country, in fact to some degree in large part my relative limited success at the u.s. conference of mayers has much to do with his advice on how to talk and which mayers are effective to have been there a long time and can help me establish a voice on the national level with the other mayers, as we try to complete the things that we are doing here locally. we have given that a great voice and so i just wanted to take this opportunity, on these closing ceremonies to praise a man that i think has done so

much and more. i appreciate it even more deeply, every single day that i am responsible for running this city, how much more he has done and how incredible, even today, in the terminal and something that has been in struggling and planning for many, many years, we can lft almost see the tears in our eyes that blesses the city and these are projects that mayor brown has done over and over and over again in all parts of the city. and i will never forget, though, that when he was mayor, and we were doing mission bay together and that was my golf driving range and he was or had this vision, of turning it in from that desolate golf ball place to something that would welcome in today. 129 bio tech companies, lo
